I am curious to know who's here makes own fuel? and you don't mind I would like to know your experience. How long you have been making it, what type of oil do you use and what percentage of Nitro are you using, and what size and type of engine are you using it on?

I have made fuel many times. Best to do it in 4 to 5 gal batches. Then dump into 1Gallon jugs. That way it is consistent for multiple gallons. I have had the best performance using Klotz heliglow oil. I blend at 20% oil and 20% nitro for 90 size and up. 25% nitro and 21% oil on smaller motors. Never needed 30% nitro with slightly lower oil content. Also keeps the model cleaner.

Percentages based on volume or weight ?

To be honest I like 30% Nitro only because I am used to it, however I will try 25% just to see if I like it. As for the batches, I think the I might have contaminated Methanol, so I ordered Hydrometer to test the remaining of methanol that I have left. On my first test I did use Klotz and it seemed to run fine, I did not have engine quit not even once and the transition was smooth. When I changed oil (Thor), that's when I have noticed the change in performance. Nonetheless, I think I might have some water in methanol, will see after the test.
